CALCULATOR · TOLERANCE
ISO Fit Tolerance Calculator (ISO 286)
Calculates hole and shaft tolerances and fit type based on ISO 286-1:2010.
Standard
ISO 286-1:2010
JIS Equivalent
JIS B 0401
HOW-TO How to Calculate ISO Fit Tolerances +
- Enter the nominal diameter in mm.
- Select the fundamental deviation (e.g. H, g) and IT grade (e.g. 7, 6) for hole and shaft.
- Tolerances and maximum/minimum clearance or interference are calculated automatically.
- Use the preset buttons to quickly select common fit combinations.
